In the R scripting language, how do I write lines of text, e.g. the following two lines
Hello
World
to a file named "output.txt"?

fileConn<-file("output.txt")
writeLines(c("Hello","World"), fileConn)
close(fileConn)

Thanks. I've been messing with sink() and message() for half an hour. This is way easier.

Mark - what If I have several threads all of which I would like to add lines to the same file? (The issue being is that you can't have more then one connection to a file, If I am not mistaken)Thanks.

@Tal, that is an excellent question, you should post it as a new, separate question so it'll get some attention. There are much more knowledgeable R programmers around here than me!

A:
Actually you can do it with sink():
> sink("outfile.txt")
> cat("hello")
> cat("\n")
> cat("world")
> sink()
hence do:
> file.show("outfile.txt")
hello
world

Now, don't be so hard on yourself... there are plenty of selfhandicaping moments in my R programming history! =)And @Mark's solution is pretty neat, so I recommend that you stick with it!
